28 designates a seat-bar which is ivotally mounted as by a transverse pivot-b0 t 29 in a saddle 30 clamped upon the offset axle centrally thereof. The rear end of said bar is downwardly ofiset a slight distance and provided with an 0 erators seat 31; while the forward end of said bar *has pivotally mounted thereon a transverse equalizer bar 32, the ends of which are adjustahly connected by depending chains 33 with the for- Ward ends of the plow-beams, the lower ends ofsaid chains having hooks 34 adapted to engage any one of a series of'eyes 35 formed in castings 36 bolted to the ends of the plowbeams.

""As seen in Fig. 2 the ends of the equalizer bar 32 are provided with a plurality of chainengaging apertures to accommodate the lateral adjustment of the forward ends of the plow-beams in the frames 10.

To the under sides oftlie plow-beams are swiveled stirrups 37; while rings 38 attached to the upper sides of said plow-beams are adapted to engage hooks 39 depending from the inner ends of the pole, which support the plow-beams in elevated position out ofcontact with the grouml when traveling to and from the field of operation.

The bent portion (5 of the axle is always inclined forwardly of the vertical. plane of the wheelspindles, the degree of angularit y being determined by the adjustable connection of the side-bars 21 with the axle, according to the weight of the operator, the heavier the operator the greater being the angle of inclination of the axle from the vertical, and. vice versa, in order to properly balance the machine. Similarly, the desired lifting effect on the plow-beams is obtained, according to the weight of the operator, by hooks 34 to the proper eyes 35 longitudinally of the plow-beams; said hooks being connected 1n the rearmost eyes for the lightest operators, and in the foremost eyes for the heaviest operators. it will also he observed that the apparatus as described and shown effects a perfect balancing-of theplow-beams by the weight of the operator, without requiring the use of springs, ratchets, gears, etc., such as are at present extensively employed for this purpose. 7

In theoperation of the cultivator, the operator is able'to nicely regulate the downward pressure upon the plows or shovels by the relative amounts of pressure applied through the seat 31 and the stirrups 37, respectively. By means of the equalizer bar 32 and the seat-bar he also has perfect control over the vertical, as well as the lateral movements of the plows, being able to swing either independently without affecting the other,

connecting the since the raising of either plow, through the increased downward pressure upon the seat 31 occasioned thereby, is accompanied by an elevation of the bar to an extent that offsets the downward movement of the opposite end of the equalizer bar connected to the opposite plow. The connection of the stirrups to the plow-beam instead of to the seat-bar enables the plows to be largelypontrolled by the'feet and legs of the operator instead of by his hands and arms. I

While I have herein shown the plow-beams as of iron, and of skeleton form, it will be understood that wooden or other forms of beams. may be employed.

I claim:

, 1. In a wheeled cultivator, the coinbination with a centrally offset axle and a twinbeam pole connected thereto at its inner end, of a de'iending inverted U-shaped yoke the vertical sides of which are bolted directly to the beams of said pole, plow-beams pivotally connected at their forward ends to the lower ends of the sides of said yoke, a seat-bur pivotally mounted on the oifset band of the axle and having a seat at its rear end, and connections between the forward end of said seat-bar and said plow-beams, substantially as described.

2. In a wheeled cultivator, the combination with an axle and a twin-beam pole connected thereto, of a depending yoke directly connected to said pole, the sides of said yoke having pivot-sumiorts extending laterally thereof, plow-beams mounted in said pivotsupports with capacity for both vertical and lateral swing, uprights adapted to receive the hitch of the team mounted on the lower ends of the sides of said yoke, an equalizerbar v a draft-bar ('omieetmg the latter centrally with the axle, and links connecting the ends of said equalizer-bar with the upper ends of said uprights, substantially as described.

,3. in a wheeled cultivator, the combination with a centrally oll'set axle and a pole connected thereto, of a depending yoke directly connected to said pole, the sides of said yoke havingextending laterally thereof, plow beams mounted in said frames 0:1 vertical and horizontal pivots, and frame-bars extending from the lower sides of said pirot-supporting frames and connected directly to the horizontal hub and intermediate portions of the axle, respectively, substard ially as described.
